Summary: Sedimentary organic matter provides carbon substrates and energy sources for microorganisms. The molecular composition and distribution of dissolved organic matter (DOM) and its interactions with microbes in deep-sea sediments remains poorly understood. This study analyzed the molecular composition of DOM and its relationship with microbes in sediment samples from the South China Sea. Results showed niche differentiation on a fine scale in different sediment layers, indicating correspondence of microbial community composition with geographical isolation and organic matter availability. The close relation between sediment DOM distribution and microbial community highlights the complex dynamics of recalcitrant DOM (RDOM) in deep-sea sediment and water column.

Summary: Global warming is causing increased greenhouse gas release from Arctic soils, potentially changing the Arctic from a carbon sink to a future source. It is important to understand the factors controlling soil microbial community structure and activity to accurately predict future greenhouse gas release. Soil conditions, such as salinity, influenced by changes in Si and Ca concentrations due to climate change, can affect microbial activity and CO2 production in Arctic soils.

Summary: The study explored the vertical distributions of microbial community and N-transforming microorganisms in an intact sediment core from the West Philippine Basin, revealing depth and organic matter as key environmental variables driving microbial community structure and nitrogen transformation processes in deep-sea sediments. The findings suggest that nitrification and denitrification are the dominant nitrogen transformation processes in the surface and deeper sediments respectively, shedding light on the role of deep-sea microbes in nitrogen cycles.

Summary: Arctic deltas are ice-dominated systems that are influenced by land ice, permafrost, and sea ice. They are highly seasonal and frozen for most of the year. The sediment and carbon fluxes in Arctic deltas are lower compared to deltas in lower latitudes, and their morphodynamics are also subdued. Climate change will cause Arctic deltas to transition away from ice dominance, leading to unknown consequences for their morphodynamics and carbon cycling.

Summary: The Arctic is undergoing rapid warming, resulting in the reshuffling of seabird species communities and their poleward expansion. Analysis of long-term monitoring data from Svalbard archipelago showed an increase in temperate species and a decline in Arctic species, confirming the shift towards a temperate state in the Arctic fauna.

Summary: Lake sediment microbial communities play a crucial role in mediating carbon diagenesis, especially in regard to methane production. A study conducted across 22 lakes found that the diversity and richness of non-methanogen community in sediment microbial communities were significantly correlated with the response of sediment methane production to changes in organic matter supply. This experimental evidence demonstrates that differences in sediment microbial communities influence the response of methane production to changes in organic matter availability.

Summary: This study identified 372 differentially expressed circRNAs in peripheral blood mononuclear cells (PBMCs) of children with asthma. Among them, a circRNA called circS100A11 was highly expressed in monocytes and significantly upregulated in children with asthma. Further experiments demonstrated that circS100A11 promoted M2a macrophage activation by enhancing translation of its host gene, S100A11, and exacerbated lung inflammation in a mouse model of asthma. The study also found that circS100A11 competitively bound to CAPRIN1 to promote S100A11 translation, thereby enhancing M2a macrophage activation.

Summary: Sebastes schlegelii is a fish species with high economic value, but the outbreak of diseases in its aquaculture industry has caused significant economic losses. Study of the fish immune system, particularly the immunoglobulin genes, can provide insights into the immune response to pathogens and contribute to the development of prevention and control methods. This study successfully identified and cloned the immunoglobulin heavy chain genes (sIgM, mIgM, sIgT, and mIgT) of S. schlegelii, revealing their high conservation during evolution.

Summary: Recently, the Gram-negative pathogenic bacterium Vibrio anguillarum has become a major obstacle to the turbot aquaculture industry due to its global distribution, wide host range, and potential devastating impacts. This study conducted comprehensive analyses of whole-transcriptome sequencing in turbot liver infected by V. anguillarum and found differential expression of circRNAs, miRNAs, and mRNAs. Interaction pairs between miRNA-circRNA and miRNA-mRNA were predicted and circRNA-related ceRNA regulatory networks were constructed. The study identified novel target genes for disease prevention and control in turbot.

Summary: Cell-to-cell communication through gap junction channels is essential for coordinating cellular functions in multicellular tissues. This study identified 48 members of the gap junction protein family in Sebastes schlegelii, classifying them into connexin and pannexin types. The connexins were further divided into five subfamilies. The study also revealed the protein structure and interactions of GJs, and showed that GJ proteins were highly expressed in intestinal tissues and regulated after bacterial infection. The findings provide valuable insights for further understanding the function of GJ proteins in S. schlegelii.

Summary: Six IKK genes were identified in turbot, and they were widely expressed in various tissues. After bacterial infection, these genes showed different expression patterns in mucosal tissues, indicating their potential roles in maintaining mucosal barrier integrity. Protein-protein interaction network analysis revealed that most interacting proteins of IKK genes were related to the NF-kappa B signaling pathway. Functional experiments confirmed the involvement of SmIKK alpha/SmIKK alpha 2/SmIKK beta in the activation of NF-kappa B in turbot.

Summary: This study retrospectively analyzed the clinical characteristics and underlying causes of 551 hospitalized children with recurrent pneumonia from January 2016 to January 2021 at the Children's Hospital of Fudan University. The majority (87.7%) of the children had underlying causes, with recurrent aspiration, primary immunodeficiency, and congenital heart diseases being the most common. Genetic defects were identified in about a quarter of the patients. Primary immunodeficiency, primary ciliary dyskinesia, bronchiolitis obliterans, and the age of >3 years at diagnosis were risk factors for severe outcomes. Aspiration and an abnormal family history were risk factors for rehospitalization.

Summary: In this paper, a new run-time monitoring technique is proposed to detect hardware Trojans (HT) on working field-programmable gate array (FPGA), which can enhance the hardware security of IoT devices. The technique places multiple temperature sensors on FPGA and collects their values at each time interval. A predictive model is constructed to estimate the real-time distribution of sensor frequency. If the difference between the predicted value and the real one exceeds a dynamically updated threshold, an HT activation is reported. The experiment results demonstrate that the technique achieves high detection accuracy (>= 98%), low false negative ratio (<= 1.5%), and zero false positive ratio under various FPGA HT benchmarks.

Summary: Spatial transcriptomes were used to study the transcriptomic landscape in the posterior intestine of Sebastes schlegelii following Edwardsiella piscicida infection. A molecular regionalization of the posterior intestine was observed in the healthy condition. After bacterial infection, immune-related genes were predominantly found in the mucosa layer. The expression of regeneration-related genes suggested the constant proliferation of new cells in response to pathogen invasion, while increasing microbiota communities indicated their role in maintaining intestinal integrity and shaping the mucosal immune system.
